CHARLES I. PENROSE, `OF CHATHAM, NEV YORK.

BOLT-LOCKING DEVICE.

SPECIFICATION forming part of Letters Patent No. 403,131, dated May 14, 1889. Application filed January 19, 1889. Serial No. 296,841. (No model.)

ToV all whom it may concern.-

Be it known that I, CHARLES I. PENRosE, acitizen of the United States, residing at Chatham, in the county of Columbia and State of New York, have invented certain new and useful Improvements in Bolt-Locking Devices; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in bolt-locking devices, and more particularly to the means of securing the bolts used in connection with the iishplates in connecting adjacent railway-rails; and it has for its object to provide a simple and inexpensive and at the same time durable and efficient means whereby such bolts may be locked securelyin position, and which will insure the bolt being securely retained in position without the aid of the nut which is commonly employed.

To these ends and to such others as the invention may pertain the same consists in the peculiar construction and in the novel combination, arrangement, and adaptation of parts, all asl more fully hereinafter described, shown in the accompanying drawings, and then particularly defined in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part .of this specification, and in which- Figure l is a side elevation of the ends of two adjacent railway-rails and fish-plate, the bolts being shown'as locked in place in accordance with my invention. Fig. 2 is a transverse section upon the line :n .fr of Fig. l. Fig. 3 is a side view of one of the iish-plates removed. Fig. 4. is a detail perspective view of one of the locking-levers detached.

Reference being had to the details of the drawings by letter, A represents a railwayrail of the ordinary and well-known construction and provided with holes for the reoeption of the bolts used in securing in position the ish-plates B and B. The fish-plate B, which is used upon the inner side of the rails and against which the head of the bolt C abuts, is in all respects similar to the iishplates that are commonly' used in this connection. At a point near the end of the bolt C opposite that provided with the head ct a transverse hole is provided, for a purpose which will presently appear.

D is a short metallic lever bifurcated at one of its ends, as shown. The extreme outer ends of the bifurcated arms b are cam-shaped and provided with transverse 4holes o for the passage of the pin or bolt el, which is passed through said holes and also through the hole in the end of the bolt C which is retained between the bifurcated arms, as shown.

The fish-plate B is provided upon its outer face at points both above and below and adjacent to the bolt-holes e with recesses or outaway portions f for the reception of the camshaped ends of the locking-lever D, as will be readily understood.

The operation is simple. The rails having been placed in position, the fish-plate B is placed upon the inner side of the rails and the plate B upon the outer side, and the bolts C are passed through both the plates and rails from the inner side. The levers D are then placed in position upon the outer ends of the bolts and secured thereto by means of the bolt or pin d. When the parts are thus connected, it will be at once seen that the camshaped ends of the bifurcated lever-arms will iit within the recesses f upon the outer face of the fish-plate B', and that by simply turning th`e lever so that its body will be parallel with and adjacent to the outerv face of the iish-plate the bolt will be securely drawn into place and will be retained until the lever is thrown outward or into a position at substantially right angles with the length of the iishplate.

Having thus described my invention and set forth its merits, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination,with the adjacent ends of two connecting railway-rails and the iishplates upon either side thereof, of the bolts passed through said plates and rails, the bifurcated lever adapted to embrace the outer end of the bolt, and the pin or bolt connectro fish-plate B', and a pin or bolt passed through y said cern-shaped ends of the lever and through the opening in the end of the bolt, substantially as and for the purpose described,

In testimony whereof I affix my sign :tture in presence of two Witnesses.

CHARLES I. PENROSE.
